Alex Chalk: I thank the right hon. Gentleman for his remarks. He is absolutely right that this is an announcement of such moment that it will require cross-party and generational support. It is important to note precisely the scale of what is being proposed. As he rightly indicated, this is about not simply the sale of a weapons system, but the growth of a capability across continents and across generations. With scale comes opportunity: having that trinational approach builds the resilience of the supply chain and of the industrial capability, which benefits Australia, of course, and the United Kingdom.
The right hon. Gentleman asked about investment. I am pleased to note that, in the last financial year, £2 billion was invested into Barrow-in-Furness and Raynesway, as he will have seen, because I think he has had the opportunity to visit both recently. There will be further investment to come, partly as a result of what has been announced recently, and in the years to come, which echoes my point about it having to be sustained and continued. He is right, of course, to reference the fact that, in the document that accompanies the announcement, a copy of which I am sure he has seen, the Australians have indicated their agreement to make a proportionate investment in UK infrastructure.
The right hon. Gentleman is correct to ask about co-ordination, because this has to be co-ordinated. The way that happens is, first and foremost, to ensure that the Australian experts who need to develop that expertise, as they have candidly acknowledged, spend time in the UK—in Barrow and Raynesway. Indeed, this Thursday, I am looking forward to going to Barrow with the Premier of South Australia, where the first SSN-AUKUS for the Royal Australian Navy will be built.
The right hon. Gentleman raised the issue of AUKUS pillar 2. I have had the opportunity to speak to my opposite number here in the UK to discuss precisely that. There are a number of aspects to it, as he indicated, such as hypersonics, AI and underwater technologies, and further detail will be explored in due course. To his point about other countries, I can say that, unlike  pillar 1, which is not open for engagement beyond the three nations, we will of course consider the interest that other nations have expressed in pillar 2.
As is well expressed in the fact sheet that accompanies the announcement, AUKUS—whether pillar 1 or pillar 2—is designed to show:
“our shared commitment to a free and open Indo-Pacific and an international system that respects the rule of law, sovereignty, human rights, and the peaceful resolution of disputes free from coercion.”
That is what our nations stand for, and that is what AUKUS will deliver.
